7 Claims.

This invention relates to improvements in dishes and covers, moreparticularly, although not solely, adapted for refrigerator use.Seamless drawn steel enameled dishes and covers of various round andoval shapes now in every day use are objectionable due to the fact thatconsiderable space is lost when a number of dishes and their covers areplaced on a shelf and more particularly refrigerator shelves in, whichthe storage space is very limited and it is desirable in homerefrigerators to accommodate a considerable number of different dishes.It is also desirable to eliminate seams and joints in dishes and coversadapted to hold food for any length of time due to the fact that it isextremely diicult to completely clean seams and joints and the foodlodged therein will soon contaminate other food placed in the dish orresting on the cover.

It is one of the objects of the present invention to overcome the beforementioned objectionable features and provide a dish and cover ofapproximately square shape which are entirely free from joints or seamsand which will permit the placing of the greatest number of dishes andtheir covers in a limited area to occupy a minimum amount of space.

A further object of the invention is to provide a dish of squareseamless form inhorizontal section and having slightly rounded cornersand tapered side portions to permit nesting of a plurality of the dishestogether.

A further object of the invention is to provide a dish ofsquareformation having comparatively deeptapered side portions andoutwardly and downwardly extending upper edge portions.

A further object of the invention is to provide a dish cover in squareformation shaped to snugly fit its dish and permit the placing of otherdishes on top of the cover, and furthermore to provide a dish coverwhich may also be used as a dish itself either side up.

A further object of the invention is t0 provide a dish and cover ofsquare seamless formation which are of simple construction, are strongand (o1. ess-59) Fig. 2 is atransverse sectional view thereof;

Fig. 3 is a diagrammatic top view of arefrigerator showing a number ofround dishes of ordinary construction therein; 1

Fig. 4 is a similar view showing the greater number of the improvedsquare dishes which may be accommodated in the space of the same size;and

Fig. 5 is a sectional view oi the cover shown in inverted position whenused as a dish.

Referring to the drawing, the numeral 5 indi- 8 and slightly roundedcorners 9 to permit convenient nesting of the dishes and to eliminatesharp corners in which food might lodge. The upper edge portions of thesides curve outwardly and downwardly to form anges 10 which reinforceand give an ornate appearance to the dish. Particular attentionis'directed to the fact that the dish is of one piece construction andthat the corner portions are entirely free from seams or joints so thatsmooth interior and exterior surfaces are provided thus forming asanitary dish very desirable for holding food.

The cover l1 of the improved dish is also of rectangularfshape withrounded corners 12 and is formed with edge corrugations 13 of S-shape incross section. The outer corrugation is upwardly curved to form arectangular groove14 into which the upper edge of the dish extends whenthe cover is place'd thereon, as shown in Fig. 2. The inner corrugationis curved downwardly to form ashoulder or bead-15 which extends into thedish close to the upper edge thereof and prevents said cover fromaccidentally sliding off the dish, and also permits nesting the coverstogether. The inner portion 10 of the cover is approximately of flatshape so that-when in 'inverted position as shown in Fig. Q the covermay be used as a plate or dish, the oppositel side portion of thegrooved cover part forming a supporting rib or bead 14 for said cover.The said cover is also formed of sheet metal 17 covered on both sideswith enamel 18 baked thereon.

AFromthe foregoing descriptionit will be seen that the invention is ofvery simple construction and that a given area will accommodate agreater number of dishes and their covers'of the improved form and ofgreater capacity than the ordinary dishes and covers now in general use.

`For convenient sliding or lifting of the. dish and cover together, theassembly may be grasped between the fingers, for example, with the thumbresting against the side of the rib 1 4' which is in common with theouter wall of the upwardly facing groove in the cover, while placing theforenger against the exposed portionv of the ange 10, preferably usingthe other fingers braced against the adjacent side of the dish towardits bottom.

The upwardly facing groove formed on the upper side of the shoulder 15constitutes a peripheral trough which will collect and retain liquidswhich may be spilled on to the dish from other receptacles in uppershelves of a refriger- In this way such spilled liquids do .not enterthe dish to contaminate the contents thereof, nor is it left to trickleover the edge of the cover on to other receptacles beneath the dish oronto the shelves or bottoml wall of the refrigerator.

When the cover is used in the inverted position of Fig. 5 the shoulder15 constitutes a lower -barrier between. the field of the cover and therim receiving groove 14. This barrier prevents liquid or other smallparticles from getting into the groove 14. This feature is of especialadvantage when the dish and cover are used in inverted position for thestorage of meats, for the lifted off.

' When the pan is oft theinverted cover, the outer groove forms a cleanisolated finger hold groove free from juices, gravy and particles of thefood carried on the inverted cover, which makes the cover particularlyadvantageous for use as a tray after the'removal of the dish which hasbeen used to enclose the contents of the inverted cover for storage.While the vpan is in place on the. inverted cover, the spacing of theoutermost flange of the cover from the side wall of the dish also"affords a convenient nger hold for carrying the assembled unit.

`What is claimed is:

1. sheet metal dish and cover of rectangular formvin horizontal sectionand having seamlessv corner portions being non-folded and formed ofsingle thicknesses of metal, the cover having a rectangular groove onone side to receive the upper edgeportions' of the dish and beinginrectangular form in horizontal section and. having seamless cornerportions formed of single thicknesses of metaLthe cover havingrarectangular groove on one side to receive the upper edge portions of thedish and a rib on the other side to support thefcover when in' invertedposition, said groove and rib being formed by reverse curves in themetal. Y
